He was a man of true
piety and genuine modesty, and was urged by his father to attend
Rav Chisda's lectures diligently and to profit by his acumen. At first, however, Rabbah held aloof because matters were discussed which did not appeal to his earnest nature. But later he became closely associated with Rav Chisda, and was appointed judge under him; subsequently the two discussed
aggadic subjects together. After the death of Rav Chisda, Rabbah became the head of the Academy of Sura, though he apparently held this position without the approval of the
exilarch. His general relations with the exilarchate were by no means friendly, and he declared himself independent of its authority. ==Teachings==
